This 12" Dobsonian is in good condition.


  • This clever push-to Dobsonian reflector telescope can lead you to more than 14,000 celestial objects with its included IntelliScope Computerized Object Locator
  • 12" aperture f/4.9 reflector telescope gathers enough light for bright close-up views of the Moon and planets
  • Big reflector telescope provides sharp views of faint deep sky objects like galaxies, nebulas and star clusters
  • Simple Dobsonian point-and-view ease of use plus IntelliScope smarts equals a telescope for a lifetime
  • Includes 2" Crayford focuser, two Sirius Plossl 1.25" eyepieces, a 9x50 finder scope, eyepiece rack, collimation cap, Starry Night software and more!


The Orion SkyQuest XT12i Computerized IntelliScope takes big-aperture astronomy to a new level of performance and user-friendly fun. With design ingenuity and technical sophistication that make competing models yesterday's news, it will WOW even the most star-savvy enthusiast. And now the XT12 SkyQuest XT12i Computerized IntelliScope comes with a 2" Crayford-style focuser for smooth focusing performance.

Its prodigious 305mm (12.0"), Pyrex parabolic primary mirror pulls down 42% more light than 10" optics and 126% more than 8" optics. What's more, the XT12i is an IntelliScope. Which means you can plug the included IntelliScope Computerized Object Locator into the telescope's base and you're ready to find and view any of 14,000 celestial objects with the push of a button or two. Sound easy? It is.

Intelliscope Dob Chart

The Orion SkyQuest XT12i Computerized IntelliScope is outfitted with an open-ventilation, aluminum mirror cell that features 9-point floating support and mounting holes for an optional cooling fan. The 2" Crayford-style focuser accepts both 2" and 1.25" eyepieces. The Crayford-style focuser is smoother and more accurate than a rack-and-pinion focuser. Roller bearing construction eliminates image shift due to drawtube "rocking". Upgraded metal focusing knobs with rubber grips give you a great feel, and a thumb screw for locking the focus position and adjusting tension give you greater control. The focuser includes an adapter for 1.25" telescope eyepieces.

You also get a 9x50 dovetail finder scope and our exclusive navigation knob for easy slewing. The made-in-USA base boasts non-stick PTFE azimuth bearings for smooth, "stiction-free" movement and a springless, adjustable CorrecTension system for always-perfect tube balance and motion.

Although it's big, the Orion XT12i is easily manageable by any fit individual. The optical tube, which uncouples from the base for transport, is 4' 10" long and 50 lbs. The base is 30" tall, 26" wide, weighs 33 lbs., and has a convenient carrying handle.

If you're ready for some outrageous aperture, get the smartest big telescope to come along in years - the Orion SkyQuest XT12i Computerized Intelliscope! Mirror, optical tube, and base packaged separately; some assembly required.
